LIGHT RAY AND MASSAGE THERAPY Amos R. Marty, Marion, Ohio. Appiication' December 11, 1 946, SerialNi).1 1-555?v 7 Claims.

This invention relates to light ray and massage therapy.

Among the objects of the invention is the provision of a manual device for the application of vibratory massages, inira--red light rays and heat to the human skin.

Another object is to accelerate the circulation of the blood, stimulate the muscular" and vascular systems and build up the nerve energy of the human body.

A further object is the simplification and noiseless operation of the vibratory means and the mechanical and electrical control of the capacity of the infrared light and heat source.

Other objects and advantages will appear as the" description proceeds. In the specification and the accompanying drawings, the invention is disclosed in its preferred form. But it isto be understood that it is not limited to this form; because it maybe embodied in modifications within the spirit of the invention as we defined in the claims following the description.

Inthe one sheet of drawings:

Fig. 1 is a side elevation invertical section on the line I-I, Fig. 2, of a device constructed in accordance with this invention.

Fig. 2 is a plan view from above of the same. with the cover omitted.

Fig. 3' is a fragmentary detail in vertical section on theline- I II -III, Fig. 2, showing the mechani cai adjustment of the infrared ray and heat assembly.

Fig. 4- is adetail in vertical section of a modifled form of massage member.

In detail the structure shown in Fig. 1, comprisesthe cylindrical body I, open at the top and bottom and having the integral handle base 2 extending laterally from the body. The cover 3 closes the top of the body and the handle base and is attached thereto by the screws, such as I, threaded into the lugs such as 5, integral with the base 2 and the top of the body. The base has the transverse bridge 5. extending across the diameter oi the body, and has the. lugs 1, 8, extending outward therefrom.

The infra-red light and heat source comprises the lamp 9 having its base extending into the socket [0, wherein it is fixed by the bayonet connection such as H. Such lamps are conventional in this. art and have the upper portion of the parabolic glass silvered to reflect and. concentrate the. rays given off. by an internal filament.

The. socket H is fixed within the adjusting bar L2 having. its opposite ends guided, in the: longis iron armature- 33 is welded or 2 tudi'nal; slots; I3, I14. extending from the bottom of. the-body" I ,up: to the levelv of. the bridge 6.

The:- spring; latches; I15, iii. are fixed to the underside of. the. bar l2, seeFig- Biand: extend down ward: and have the: tapered and sharpenedends extending: into the slots. I3 H, the inner edges of which. they normally engage and lock the bar l2 and lamp 9 in selected position. These latches have the buttons: I51, I18; extending through theslots l3, l4. Whenzthese: buttons are pressed inward by the thumband finger of the operator the latches are: disengaged. and the lamp may be longitudinally adjusted: within: the body I.

Theannular massage member ii) is. mounted uponv the lower ends of the; legs 20, 2i of the U-shaped yoke 22, with the massage member axially alined with. the lamp- 9; The lugs such as 23 on top of the massage. member detachably engage in the sockets 24. 25 on the lower ends of the legs-of the yoke. A modified form of massaging member 19K is shown in Fig. 4, and may be substituted for thelmember l9 by inserting the lugs 23X into the sockets 24, 25.

The yoke 22 has the slotted central stud 26 fixed to the underside of the yoke and straddled over the center of the flat spring 21, to which it is welded or otherwise fixed. The opposite ends of the spring are likewisefixed in the split studs 28, 29' that are fixed to the lugs 1, 8, of the bridge 6.

The laminated iron" core 30 is firmly mounted onthe base 2 in substantialalinement with the yoke 22, within the handle and has the coil 3| surroundingthe center pole 32 of the core. The fixed on the leg 2| of the yoke, and extends. into the handle with its free end alined with. the face of the center core 32 and normally spaced outwardly therefromby thespring 21 The gap between the face of the. core. and: the: armature is predetermined before the laminated core; is. screwed tight to the base 2: The vibrations of the. armature 33 transmitted. through the: legs 20;. 21:. give, a torsional oscillating-1 eflect. to; the massage member i9.

The electric: circuit. includes the incoming and outgoing wires 34... 35 from. a. sourcev of A. C. cur rent, not shown. The current; flows in over the wire: 34,, through the. coil 31'. and back to the source over the wire 35. This energizes the lamihated core which magnetically attracts the armature 33 to: the: taco 32 of the core, against the tensionv of the: spring 21;. causing an oscillatory vibration oi the yoke 22 on the center axis 26, which is tmnsmlittedv to the: messaging member 19. The amplitude of the vibration of the armature 33 may be mechanically adjusted by the screw 36 threaded in the side of the base 2. This adjusting screw has the rubber insert button 31, for silently contacting the armature. If no vibration is desired the screw 36 is turned inwardly until it jams the armature 33 against the face of the core 32. For a more delicate adjustment of the amplitude of the magnetic attraction the dampener 38 is provided. This consists of a laminated iron block interposed between the face 32 of the core and the inside surface of the side of the base 2. The dampener may be advanced across the face 32 by the stud 39, extending through a slot 40 in the base, against which it is set by the knurled nut 4| threaded on the stud. The dampener as shown is set for minimum vibration of the armature 33. By sliding the dampener out of contact with the face 32, maximum vibration is restored to the armature.

Lamps such as 9 are designed to operate on reduced voltage which may be controlled by a rheostat or more simply by shunt circuits, such as 42, 43, tapped into the coil 3I at appropriate points for conducting lower voltages to the filament of the lamp. These shunt circuits are selectively chosen by a single pole switch such as diagrammatically shown at 4 3. This switch mechanism is assembled on the inside of the body I at any convenient point and may be operated by the protruding button 45, within easy reach of the thumb of the operator, for varying the intensity and volume of infra-red rays emitted by the lamp 9. In this manner a range of voltages is available from sixteen to twenty volts,

more Or less, in accordance with the rating of K the lamp 9.

In addition to the electrical variation of the lamp output just described, the lamp may be raised and lowered within the body I, varying its proximit to the skin of the patient beyond the massaging member. This is accomplished by depressin the buttons I'I, I8, between the thumb and finger of th operator, which releases the latches I5, I8, permitting the lamp mounting to be raised or lowered for meeting the light and heat therapy indicated by the patients skin condition.

If it is desired to massage the skin without the application of the light and heat rays from the lamp 9, the switch button 45 is moved to open the switch at 44, which switches off the lamp without affecting the vibratory massage motive means.

If light and heat treatment is desired without massage the vibratory controls at 35 or 4| be adjusted to stop the vibration of the armature 33, as previously described. The light emitted by the lamp 9 is concentrated by the reflector coating on the bulb above the filament and projected downwardly through the center opening in the annular massaging member I9.

Surplus radiations of heat from the lamp escape laterally through the slots I3, I4, and upwardly through the perforations; in the cover 3; which also permit escape of temperature arising from the coil assembly at 3I. This escape of heat at 46 has an aspirating eilfect, drawing cold air into the handle at the opening 41, in the base 2.

The glass sealed lamp 9 is preferred as the source of infra-red rays and heat; but open hot filaments and similar sources may be substituted for the lamp. The fire hazard of such open filag e s s p c y eliminated by the enclosing ody I.

Various types of massage members are supplied as accessories. That shown in Fig. 1 is suitable for firm muscular areas, while the modification shown in Fig. 4 is adapted for deeper depression into facial, neck, abdominal and soft fatty tissues, for dissipating excess fat by massage and heat by more concentrated application on smaller areas. For sensitive or bony structures the face of the ring may be modified by omitting the knobby projections shown. Where heat therapy without massage is indicated and emollients are applied to the skin, the massaging member such as I9 may be omitted to give a wider spread of the heat rays from the lamp 9, through the open bottom end of the body I.

While it is preferable to adjustably mount the lamp 9, or other heat source within the body I, this source may be mounted externally on the body I, in adjustable relation to the skin area b neath the heat source, without departin from the spirit of the invention.
